Which of the following is NOT an example of heredity?
Lions show their cubs how to hunt for prey
Bacteria reproduces asexually to create cells identically to their patent
A girl has red hair just like her mom
A red geranium plant is bred with a whiter geranium plant which produces a pink geranium plant.
What would be a possible DISADVANTAGE of asexual reproduction?
Ability to reproduce in the absence of a mate
Results in a low genetic variation of the species
Takes less time to produce offspring
Allows for more genetic variation in the offspring
Hydra reproduce by a process known as budding, as shown in the diagram below. This process is the formation of a new individual that is a clone of the parent. This type of reproduction is —
Sexual
Asexual
Binary Fission
Sporulation
Which of the following cell components are most involved in determining an organism’s traits?
Chromosomes
Cytoplasm
Mitochondria
Chloroplast
What is an ADVANTAGE of offspring produced from sexual reproduction?
Offspring may be unfit for the environment in which they are formed
Offspring are able to have more advantageous traits than their parents
Traits are consistently conserved from generation to generation
Offspring are smaller and more active than their parents
Which of the following scenarios of reproduction is most likely to form uniform offspring?
Pollen from one flower pollinated an egg of another flower to produce seeds
A female fish lays unfertilized eggs in a river, and the male arrives later to fertilize them
Spores are formed from two different cells, each from individual fungi organisms
An amoeba splits during binary fission into two separate cells
The unfertilized eggs of honeybees become male worker bees
Sexual
Asexual
Pollen from one flower joins the egg of another to form seeds that cover the strawberry fruit.
Sexual
Asexual
Offspring look exactly like the parent and share the same DNA
Sexual
Asexual
Which of the following is a TRUE statement.
Sexual Reproduction will have an offspring with identical DNA
Asexual reproduction will lead to more genetic variation in their offspring.
An example of asexual reproduction is when the offspring has a unique DNA.
An example of sexual reproduction is when the parents give half their traits to the offspring leading to unique DNA.
Which of the following describes Sexual reproduction?
Involves only 1 parent, offspring is identical to parent and it happens quickly
Involves 2 parents, offspring identical to 1 parent, and it is slow.
Involves only 1 parent, offspring is a mix of the parents, and happens slow.
Involves 2 parents, offspring is a mix of the parents, and it is slow
What is described below: No genetic Variation, Parent and Offspring at identical
Sexual
Asexual
Every time the bell rings, the student hurry to their next class. This is considered a .....
Inherited Trait
Learned Behavior
Something no student really does
Heredity
Heredity is defined as the passage of genetic instructions from one generation to the next. Which of the following is NOT an example of these genetic instructions in humans?
Height
Skin Color
Dimples
Spoken Language
Which of the following scenarios of reproduction is most likely to form diverse offspring?
A female cat’s body collects sperm cells from multiple mates and uses the cells all at once to generate a litter.
A bacteria cell replicates exponentially in a nutrient rich environment to generate a large colony of bacteria with the exact same DNA.
A scientist cuts a branch off of a tree and applies a root growth hormone to cause the branch to grow into a mature tree.
An individual hydra produces a bud which breaks off of the animal to form a new adult.
The amoeba is a unicellular protozoan with no fixed shape. It moves by constantly changing the shape of its body. One type of amoeba, Amoeba proteus, reproduces asexually through a process known as binary fission. The cell divides into two separate cells; the original parent cell and the new cell.Which of the following statements best describes the new amoeba cell?
The new amoeba cell only contains half of the genetic material from the parent amoeba cell.
The new amoeba cell is a different species than the parent amoeba cell.
The new amoeba cell received half of its genetic material from each parent.
The new amoeba cell is genetically identical to the parent amoeba cell.
